Question 1 of 27070

Q

Fluctuations in the pressure and temperature of the steam supplied to the first-effect of a low pressure distilling plant will cause __________.

🔍 Key Concepts

• Low pressure distilling plant operation and purpose of the first effect • How changes in steam supply pressure and temperature affect evaporation and boiling conditions • Relationship between conditions in the first effect and conditions in subsequent effects in a multi‑effect evaporator

💭 Think About

• If the steam entering the first effect is not steady, what happens to the boiling rate and pressure inside that first effect? • Do disturbances in the first effect usually stay local, or do they tend to pass along to later stages in a multi‑effect unit? Why? • Which choice best describes a chain reaction effect, rather than a local or beneficial change?

✅ Before You Answer

• Identify which option describes a system‑wide consequence rather than a local one • Eliminate any choices that incorrectly promise improved conditions (less scale, less priming, lower salinity) simply from unstable steam supply • Check which answer aligns with how multi‑effect evaporators transfer pressure/temperature changes from the first effect to later effects
